Jeremy Ashkenas' underscore.coffee vs his underscore.js (the tie to go along with jQuery's tux)

From Michael Hunger's look at CoffeeScript on InfoQ:

• Python style significant whitespace
• implicit parentheses
• no semicolons
• String continuations
• concise function literals
• YAML style object literals

• everything is an expression (returns a value)
• all variables in local lexical scope, no pollution of global scope
• simple assignment and variable declarations, destructuring assignments
• switch statements compiled to if-then-else chains
• chain comparisons
• named parameters

• variable arguments lists (splats)
• literate programming (write the code within its documentation)
• pythons range, array and object comprehensions
• existential (elvis) operator
• explicit strong binding of current self to function with => Hashrocket operator
• fast and working class based inheritance support, based on the google.inherit approach
• support for static inheritance and automatic delegation to superclass methods
• heredocs, multiline strings, literal regexps, string interpolation/substitution
• Cake a simple build system similar to Rake
• <script type="text/coffeescript"> tags, minified coffescript compiler for inline use
